One reason might be that you don't really need all that memory, but because you're holding references to not-needed variables, the garbage collector can't reclaim it. An easy way to avoid this is to break up the task executing on the backend into multiple smaller tasks that you manage through the use of task queues. If you're convinced you need all that memory, you can consider changing your backend to a higher class (B1 has only 128MB memory, but B2, B3.. etc, allow you to use more at a higher cost). You could temporarily use a higher class while you figure out how to lower your memory foot-print, either through code changes or through breaking up tasks.
